First paragraph of Easterbrook:
>The Medieval Warm Period (MWP) was a time of warm climate from about 900–1300 AD, when global temperatures were somewhat warmer than at present.
This is contradicted by your second source, which claims we can't know whether it was warmer, and that the best evidence we have shows temperatures below modern temperatures. Good job at proving your own source is full of shit.

>2000 year chart. Roman Warm Period was warmer than today.
Your own graph shows that to be false. The man who made it even says it's false:

“Since AD 1990, though, average temperatures in the extra-tropical Northern Hemisphere exceed those of any other warm decades the last two millennia, even the peak of the Medieval Warm Period”

That's because Ljungqvist reconstruction agrees with the other reconstructions showing today's temperatures exceed the MWP. Pic related. Thank you for providing yet another proof against your own argument.
